High Throughput

  • High-powered 72 MHz transponders can accommodate exceptionally high data throughput requirements
  • Global, fixed, and steerable beams can be stacked to support requirements of a specific geographic region
  • Dual polarization provides for flexibility and increased capacity


  • On-board switching and steerable spot beams allow for urgent repositioning of resources to fulfill short notice and mobile requirements
  • Repositioning of steerable spot beams offer near real-time response, potentially in minutes from receipt of request


  • Compatible with all existing government and military X-band terminals with no modifications required


  • Guaranteed, dedicated X-band service not subject to prioritization of users
  • Redundant, secure space and ground segments for assured access


  • Caribou encrypted command and control links
  • XTAR-EUR and XTAR-LANT are controlled and monitored through an extensive, geographically-dispersed, independent and secure Ground Control System (GCS) operated at MAC I configuration
  • Leveraged, diversified ground control connectivity of fleet and payload control systems

Redundant Coverage

  • Continental United States, Europe, Middle East, Africa, South America, & the Indian Ocean region
  • The system provides overlapping coverage with regional redundancy for increased service and reliability
